NAME
     espeak-ng - A multi-lingual software speech synthesizer.

SYNOPSIS
     espeak-ng [options] [words]

DESCRIPTION
     espeak-ng is a software speech synthesizer for English, and some other lan-
     guages.

OPTIONS
     -h, --help
	    Show summary of options.

     --version
	    Prints  the  espeak  library  version and the location of the espeak
	    voice data.

     -f <text file>
	    Text file to speak.

     --stdin
	    Read text input from stdin till to the end of a stream at once.

     If neither -f nor --stdin are provided, then  <words>  from  parameter  are
     spoken, or text is spoken from stdin, read separately one line by line at a
     time.

     -d <device>
	    Use  the  specified  device to speak the audio on. If not specified,
	    the default audio device is used.

     -q     Quiet, don't produce any speech (may be useful with -x).

     -a <integer>
	    Amplitude, 0 to 200, default is 100.

     -g <integer>
	    Word gap. Pause between words, units of 10ms at the default speed.

     -k <integer>
	    Indicate capital  letters  with:  1=sound,	2=the  word  "capitals",
	    higher values = a pitch increase (try -k20).

     -l <integer>
	    Line length. If not zero (which is the default), consider lines less
	    than this length as end-of-clause.

     -p <integer>
	    Pitch adjustment, 0 to 99, default is 50.

     -s <integer>
	    Speed in words per minute, default is 175.

     -v <voice name>
	    Use  voice	file  of this name from espeak-ng-data/voices. A variant
	    can be specified using voice+variant, such as af+m3.

     -w <wave file name>
	    Write output to this WAV file, rather than speaking it directly.

     --split=<minutes>
	    Used with -w to split  the	audio  output  into  <minutes>	recorded
	    chunks.

     -b     Input text encoding, 1=UTF8, 2=8 bit, 4=16 bit.

     -m     Indicates  that the text contains SSML (Speech Synthesis Markup Lan-
	    guage) tags or other XML tags. Those SSML tags which  are  supported
	    are  interpreted.  Other  tags,  including HTML, are ignored, except
	    that some HTML tags such as <hr> <h2> and <li> ensure a break in the
	    speech.

     -x     Write phoneme mnemonics to stdout.

     -X     Write phonemes mnemonics and translation trace to stdout.  If  rules
	    files  have  been built with --compile=debug, line numbers will also
	    be displayed.

     -z     No final sentence pause at the end of the text.

     --stdout
	    Write speech output to stdout.

     --compile=voicename
	    Compile the pronunciation rules and dictionary in the current direc-
	    tory. =<voicename< is optional and specifies which language is  com-
	    piled.

     --compile-debug=voicename
	    Compile the pronunciation rules and dictionary in the current direc-
	    tory  as  above, but include line numbers, that get shown when -X is
	    used.

     --ipa  Write phonemes to  stdout  using  International  Phonetic  Alphabet.
	    --ipa=1 Use ties, --ipa=2 Use ZWJ, --ipa=3 Separate with _.

     --tie=<character>
	    The  character  to use to join multi-letter phonemes in -x and --ipa
	    output.

     --path=<path>
	    Specifies the directory containing the espeak-ng-data directory.

     --pho  Write mbrola phoneme data (.pho) to stdout or to the file in  --pho-
	    nout.

     --phonout=<filename>
	    Write  output  from  -x  -X commands and mbrola phoneme data to this
	    file.

     --punct="<characters>"
	    Speak the  names  of  punctuation  characters  during  speaking.  If
	    =<characters> is omitted, all punctuation is spoken.

     --sep=<character>
	    The character to separate phonemes from the -x and --ipa output.

     --voices[=<language code>]
	    Lists the available voices. If =<language code> is present then only
	    those  voices  which  are  suitable for that language are listed. If
	    xx-yy language code is passed, then voices with yy	of  xx	language
	    variants  are shown with higher priority than just xx. If variant is
	    passed, then all voice variants  are  shown.  If  mb  or  mbrola  is
	    passed,  then  all	voices	using  the  MBROLA voice synthesizer are
	    shown. If all is passed, then all eSpeak NG voices,  voice	variants
	    and MBROLA voices are shown.

     --voices=<directory>
	    Lists the voices in the specified subdirectory.
